Opendorse, a Serra Capital III portfolio company, has received an investment from Bears player Prince Amukamara, who is participating in the company's $3.5M Series A financing round. More than a third of the financing is coming from Amukamara and former Husker football players.

Opendorse connects marketers with athletes to secure sponsored social media activations from the world's most influential athletes. The company was co-founded back in 2013 by Amukamara’s ex-teammates — Blake Lawrence and Adi Kunalic.
